WHITE, on CHICAGO, ILLINOIS, iissienon T0 KALMAN' STEEL COMPANY, or CHICAGO, ILLINOIS, A CORPORATION or DELAWARE REENFGRCING FABRICSUPPOR-T Application filed December 6, 1926'. Serial No. 152,892.

My invention relates to concrete slab reenforcement and particularly to a device in tended to support or vertically space a fabric preliminary to the pouring of the concrete.

An object of the invention is to provide a device of the utmost simplicity, that may be quickly applied without the use of tools, and that will possess the utmost rigidity relative to the weight of metal employed. The device comprises essentially a support or stand, preferably having a broad base, and a seat at its upper end. IVith this device is associated a pair of spring wire arms,

adapted to surround a crossed bar or rod, and to hook over the bar carried 111 the seat in the support. While the device is described as particularly intended for use in supporting fabric in which the transverse and longitudinal rods are rigidly joined as by welding, it will function equally well for supporting, spacing and joining crossed bars that are not united.

I realize that the main result sought by the use of the device here disclosed has been attempted, in part at least, by devices heretofore suggested, and my improvement resides in the details of construction and ar rangement by means of which my device may be economically constructed and quickly installed.

The invention will be more readily understood by reference to the accompanying drawings, in which:

Fig. 1 is a side view of the device of my invention as installed; 7

Fig. 2 is a view taken at right angles to that of Fig. 1;

Fig. 3 is a view similar to Fig. 2, taken from the opposite direction, and;

Fig. 1 is a plan view thereof.

In the drawings, it will be seen that the supporting and spacing element consists of a sheet metal section having side flanges, 10, and a central rib, 11. The section is originally straight, as indicated in dotted lines in Fig. 1. In a preliminary operation, the rib is provided with a V-shaped notch indicated at 12 in Fig. l, and a similar notch indicated at 18. Thereafter the lower port-ion, 14: is

bent up into the full line position, with the diagonal lines of the notch in contact,'thus providing a broad flat base. In a subsequent operation, the upper portion 15 is bent into the full line position of Fig. 1. As a result of the notching in the semi-circular rib, an aperture of generally oval shape is produced, as indicated in Fig. 1. Thus when the portion 15 is bent backward into the position of Fig. 1, a double seat is provided for the bar A; that is, the bar. will have contact with the support at the points, 17 and 18. i

In order to engage and hold the bar B, I provide the spring arms, 19, 20, having hooked ends, 21, 22, and a connecting member, 23, the connecting member being held at the bend of the flanges at the junction of the'part, 15, with the main support. Preferably also, the connecting member, 23, is bent downward as at 16, to underlie the bar A, as best shown in Fig. 3,"thus providing an additional support for the bar A at a point between the points, 17, 18.

The arms, 19, 20, are constructed to originally lie in the position indicated by the dotted linesin Fig. 1 thus facilitating the engagement of the device with the'crossed' rods.

After engagement the arms areswunginto the full line position and the hooked ends are caused to engage opposite sides of the bar A. p i

The support may be very economically produced, and the Wire arms are of simple auto- 'matic machine manufacture. The assembly is likewise a simple operation.

Obviously certain modifications may be made 1n the construction shown, and I do not wish to be limited except as indicated in the appended claims.

I claim: 1. In combination, a sheet metal support having a longitudinal rib, a lateral foot and a seat for a bar at its upper end, a pair of connected spring arms, the connection between the arms being held by ears on the support, said arms being adapted to pass over and under a crossed bar and be sprung into engagement with a bar held in said seat.

2. In combination, a sheet metal support having a rib and side flanges, the rib being cut out near the upper end of the support to provide a seat, the flanges constituting ears, and a pair of connecting spring arms, the connecting member being held by the ears on the support, said arms being adapted to be wrapped-aroundacrossed bar and to engage with the bar held'in said seat. i

3. In combination, a sheet metal standhaving a central longitudinal, rib, the ribv near the uppereend'of the standhavinga.triangur lar notch, the terminal above the notch being bent backwardly and downwardly to provide a recesseand laterally spaced supports for a bar, and a spring arm having a, portion held; by the bent-over portion of the sheet metal, said springarm acting to engage and hold crossed bars.

4, Ax vertical spacer and, supportv forcrossed bars, which consists ofa rigid ribbed s sheet. metal supporti having a pair of bar seats forthe same bar at its upper end, a righteangularly. disposed, channel shaped base portion, and-spring means on said sup port: for engaging and, holding a pair ofg ;--crossed bars.-

5. A'verticalspacer and;bar support, comprising, in combination a rigid metalisupport, said; support hayinga reenforcing rib therein, a, pair ofside by side seats for the samebar, arightsangularly; disposed, channel? shaped footzatuthebase of: said support, and springmeanson saidv support 'for en: gaging andholdingmpair of'crossed bars.

6; vertical spacer and barsupport comprising a. channel shaped support, a, right-v angularly, disposed, channel shaped, foot on said i support, a pair of bar seats for a single bar formed Ollll',0f the metal at the upper; endfof: said; support and spring means on saidsupport forengaging and holding a'pair of crossed bars.
